Bubble blower

ABSTRACT

A bubble blower includes an open frame-shaped bubble blower body defining a main solution-retaining portion, a peripheral rib extending around the main solution-retaining portion and a main passage between the main solution-retaining portion and the peripheral rib, and bubble-blowing rings spaced along an inside wall of the open frame-shaped bubble blower body each defining an inner solution-retaining portion, an outer solution-retaining portion connected with the main solution-retaining portion of the bubble blower body, a sub passage between the inner solution-retaining portion and the outer solution-retaining portion in fluid communication with the main passage of the bubble blower body to form a solution supply passage.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to bubble blowing toys and moreparticularly, to a bubble blower, which is operable for blowing a largebubble and then multiple small bubbles in a first stage, and capable ofgiving bubble solution supply for blowing multiple small bubbles in asecond stage.

2. Description of the Related Art

Referring to FIG. 1, a conventional bubble blower is known comprising alarge bubble ring A, a plurality of small bubble rings C spaced aroundthe large bubble ring A, and a plurality of radial ribs B respectivelyconnected between the large bubble ring A and the small bubble rings C.After the bubble blower retains a bubble solution, the user can swingthe bubble blower slowly, causing a large bubble to be formed on thelarge bubble ring A and then moved out of the large bubble ring A. Atthis time, the user can swing the bubble blower rapidly, causing smallbubbles to be formed on the small bubble rings C and then moved out ofthe respective small bubble rings C. This design of bubble blower cansimply retain a limited amount of bubble solution for blowing one largebubble and a limited number of small bubbles once in each bubblesolution pickup cycle.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances inview. It is the main object of the present invention to provide a bubbleblower, which is operable for blowing a large bubble and then multiplesmall bubbles in a first stage, and capable of giving bubble solutionsupply for blowing multiple small bubbles in a second stage.

To achieve this and other objects of the present invention, a bubbleblower comprises a bubble blower body defining an opening and a mainsolution-retaining portion around the opening, and a bubble-blowingrings respectively extended from the inside wall of the bubble blowerbody in the opening thereof. Each bubble-blowing ring comprises a centeropening, an inner solution-retaining portion extending around the centeropening, and an outer solution-retaining portion extending around anoutside wall thereof and suspending in the opening of the bubble blowerbody. The outer solution-retaining portions of the bubble-blowing ringsare connected with the main solution-retaining portion of the bubbleblower body to form an enclosed solution-retaining loop. Further, thebubble blower body comprises a peripheral rib extending around the mainsolution-retaining portion thereof, and a main passage defined betweenthe main solution-retaining portion and the peripheral rib. Eachbubble-blowing ring further comprises a sub passage defined between theinner solution-retaining portion and outer solution-retaining portionthereof. The sub passages of the bubble-blowing rings are kept in fluidcommunication with the main passage of the bubble blower body to form asolution supply passage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 2-4, a bubble blower in accordance with the presentinvention is shown. The bubble blower comprises a bubble blower body 1,a plurality of bubble-blowing rings 2, and a handle 5.

The bubble blower body 1 is an open frame, comprising an opening 11, amain solution-retaining portion 12 formed of a plurality of teeth 121spaced along the inside wall of the bubble blower body 1 and facingtoward the opening 11, a peripheral rib 13 extending around the mainsolution-retaining portion 12 and the opening 11, a main passage 14defined between the main solution-retaining portion 12 and theperipheral rib 13, and a throat 15 located on one side thereof andformed integral with the peripheral rib 13.

The bubble-blowing rings 2 are respectively extended from the insidewall of the bubble blower body 1 and suspending in the opening 11, eachcomprising a center opening 21, an inner solution-retaining portion 22formed of a plurality of teeth 221 spaced along the inside wall thereofand facing toward the center opening 21, an outer solution-retainingportion 23 formed of a plurality of teeth 231 spaced along the outsidewall thereof and suspending in the opening 11 of the bubble blower body1, and a sub passage 24 defined between the inner solution-retainingportion 22 and the outer solution-retaining portion 23.

Further, the outer solution-retaining portions 23 of the bubble-blowingrings 2 are connected with the main solution-retaining portion 12 of thebubble blower body 1, thereby forming an enclosed solution-retainingloop 3. Further, the sub passages 24 of the bubble-blowing rings 2 arekept in fluid communication with the main passage 14 of the bubbleblower body 1, thereby forming a solution supply passage 4.

Further, the throat 15 of the bubble blower body 1 and the handle 5 arefastened together, forming a bubble blower.

Referring to FIGS. 5-7, when using the bubble blower, insert the bubbleblower body 1 into a bubble solution in a bubble solution container 6,enabling the inner solution-retaining portion 22, the enclosedsolution-retaining loop 3 and the solution supply passage 4 to retainthe bubble solution. When the user swings the bubble blower in the air,currents of air will enter the bubble blower body 1 to move the retainedbubble solution out of the enclosed solution-retaining loop 3, therebyforming a large bubble 7. When the user keeps swinging the bubble blowerin the air after formation of the large bubble 7, currents of air willpass through the opening 11 of the bubble blower body 1 and the centeropening 21 of each of the bubble-blowing rings 2. At this time, thecurrents of air that pass through the center opening 21 of eachbubble-blowing ring 2 forces the retaining bubble solution out of theinner solution-retaining portion 22 of each bubble-blowing ring 2,forming a respective small bubble 8. Because the bubble solutionretained in the enclosed solution-retaining loop 3 has been consumed bythe large bubble 7, no further large bubble will be produced at thistime. After first time small bubble formation, the bubble solution inthe main passage 14 of the bubble blower body 1 will move into the subpassages 24 of the bubble-blowing rings 2 subject to capillary effects,enabling the solution supply passage 4 to supply the bubble solution tothe inner solution-retaining portions 22 of the bubble-blowing rings 2for blowing small bubbles 8 again and again.

Referring to FIG. 5, when inserting the bubble blower body 1 into thebubble solution container 6, the two opposite lateral sides of thebubble blower body 1 is forced by the narrow mouth of the bubblesolution container 6, causing the bubble blower body 1 to elasticallycontract, and therefore the bubble blower body 1 can be smoothlyinserted into the inside of the bubble solution container 6.

Further, in the aforesaid embodiment, as shown in FIGS. 2-5, thebubble-blowing rings 2 are bilaterally arranged at the inside wall ofthe bubble blower body 1 inside the opening 11 in a symmetrical manner.Alternatively, as shown in FIG. 8, the bubble-blowing rings 2 can bebilaterally arranged at the inside wall of the bubble blower body 1inside the opening 11 in a staggered manner.

In conclusion, the invention provides a bubble blower characterized inthat the bubble blower body 1 provides inner solution-retaining portions22 for blowing additional small bubbles, and a solution supply passage 4for accommodating bubble solution for giving bubble solution supply tothe inner solution-retaining portions 22.
